Later start times Doctors say that starting school earlier in the morning prevents children and teenagers from getting a full night’s sleep, which can affect their health, safety and academic performance. The AASM recommends that teenagers should sleep 8 to 10 hours a night. But according to the CDC, almost 70% of high- school students report sleeping 7 hours or less on a regular basis. as children approach and go through puberty, their brains begin producing the sleep-inducing hormone melatonin on a delayed schedule, making it difficult for them to feel tired before 11 p.m. Because it’s normal to spend some time in bed before falling asleep, the authors write, “a teenager who goes to bed at 11 p.m. would need to sleep until 7:30 a.m. or later in order to obtain sufficient sleep.” Chronic sleep loss among teenagers has been associated with poor school performance and a higher risk for depressive symptoms, obesity, cardiovascular problems, risk-taking behaviors, and athletic injuries.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
